I saw this message earlier and hesitated to respond. I'll post my experience anyway but please keep in mind that I am not a bad guy and do not go looking for trouble.
Here's the flipside of this query. Once while working for a production company(in L.A.), I was driving around a bad part of town running errands. Turning right into a large intersection, some *sshole runs a yellow/red and almost hits me. He flips me off, I flip him off. I notice him following me throught the next couple of lights. Green late model Honda, driver was a rather wimpy looking white male in his late 30's. He was honking his horn, flipping me off and mouthing "pussy" all while signaling to pull over. I ignored him at first, but as we neared my destination, I realized a confrontation was inevitable. Now, not that I'm arrogant or immodest, but I would be lying if I didn't say I'm a rather large man (6'0 250lbs), and most of my weight is muscle. this guy behind me couldn't of weighed more than 150 lbs. So when I pulled over, I knew that just by getting out of the car, this guy would probably scram. Anyways, I pull over, he pulls up behind me. I stepped out of my car, and started for his driver side window. As I approached, he looked really nervous and scared. something was wrong, I got up to the window and in his lap was a glock of some sort. I looked at him, looked at the gun, called him a bitch and headed back for my car. Now this is the part that really gets me ! He steps out, shaking like an epileptic, and points the gun at me all the while telling me he's a cop. Now, this is in a major intersection of Los angeles in the middle of the day ! And then he drops his gun ! what an *sshole ! Needless to say I got in my truck and got the hell out of there. classic example of someone who should not own a gun.
P.S. lesson learned--- Ignore people when you drive in L.A., I'm sure I'm not the only one with this kind of experience.
